Biography

Petters teaches quantitative finance in the Fuqua School of Business and works with MBA students to promote social entrepreneurship in science and technology in Belize and the developing world. He currently holds the Benjamin Powell endowed Chair at Duke University.

Arlie Petters emigrated to the U.S. in 1979 and he has been a U.S. citizen since 1990. He earned his B.A./M.A. Hunter College - CUNY, 1986 (Mathematics, with additional major in Physics). During the summers, 1986-90 he was a Member of Technical Staff at Bell Laboratories (Lucent Technologies). He earned his Ph.D. in Mathematics from M.I.T (Massachusettes Institute of Technology-1991). From 1991-93, he was an Instructor of Pure Math at M.I.T. Dr. Arlie Petters has been a Visiting Mathematician at Oxford University Mathematical Institute, the Max-Planck-Instute für Astrophsik, and the Geometry Center of The University of Minnesota. From 1993-1998, Dr. Petters was an Assistant Professor in Mathematics at Princeton University and during 1996 to 1998 he served as co-Director of Graduate Studies in Mathematics.

In 1998, Petters was awarded Mathematics most prestigious Sloan Research Fellowship as well as a 5 year National Science Foundation Career Grant. In the fall of 1998, Dr. Arlie Petters joined Duke University, where he holds the William & Sue Gross Chair in the Mathematics Department where he is the first African American tenured faculty in the sciences/mathematics.

In 2003, he became a Full Professor at Duke University and is the first black elected
to Duke's prestigious Bass Society of Fellows..

In November 2002, he became the first recipient of the Blackwell-Tapia Prize

RESEARCH NOTES

Dr. Petters is chiefly interested in the Mathematical Theory of Gravitational Lensing and related areas (Singularity Theory, General Relativity, Theoretical Astrophysics). He has published 30 papers and one book, chiefly in the area Gravitational Lensing. It has been said that he founded the field of Mathematical Astronomy. DBelow is his research statement.

"Currently, I am working on developing a general mathematical theory of light deflection in weak gravitational fields, and investigating the observational consequences of the theorems in such a theory. This is done by addressing a series of problems touching on several aspects of gravitational lensing: multiple imaging, magnification, critical curves and caustics, and mass reconstruction. These issues are treated not only for the single lens plane case, but for any finite number of lens planes. My goal is to emphasize the stable and generic features of lensing, drawing conclusions essentially independent of the details (especially, the oversimplifying approximations and assumptions) of a chosen lens system model. To obtain such "universal'' results, one must employ tools from singularity theory. At the same time, I also analyze in-depth specific models that are physically realistic. My research involves collorations with mathematicians, astrophysicists, and computer scientists."

A first step towards the aforementioned mathematical theory appears in the book: Singularity Theory and Gravitational Lensing.
